With the rapid development of the Internet of Things (IoTs), photovoltaics (PVs) has a vast market supply gap of billion dollars. Moreover, it also puts forward new requirements for the development of indoor photovoltaic devices (IPVs). In recent years, PVs represented by organic photovoltaic cells (OPVs), silicon solar cells, dye-sensitized solar cells (DSSCs), etc. considered for use in IoTs mechanisms have also been extensively investigated. However, there are few reports on the indoor applications of perovskite devices, even though it has the advantages of better performance. In fact, perovskite has the advantages of better bandgap adjustability, lower cost, and easier preparation of large-area on flexible substrates, compared with other types of IPVs. This review starts from the development status of IoTs and investigates the cost, technology, and future trends of IPVs. We believe that perovskite photovoltaics is more suitable for indoor applications and review some strategies for fabricating high-performance perovskite indoor photovoltaic devices (IPVs). Finally, we also put forward a perspective for the long-term development of perovskite IPVs.

钙钛矿室内光伏：机遇与挑战

随着物联网（IoT）的快速发展，光伏（PV）存在数十亿美元的巨大市场供应缺口。而且，这也对室内光伏装置（IPV）的发展提出了新的要求。近年来，以有机光伏电池（OPV）、硅太阳能电池、染料敏化太阳能电池（DSSC）等为代表的被考虑用于物联网机制的光伏发电也得到了广泛的研究。然而，尽管钙钛矿器件具有更好的性能优势，但其室内应用的报道却很少。事实上，与其他类型的IPV相比，钙钛矿具有带隙可调性更好、成本更低、更容易在柔性基板上大面积制备等优点。本文从物联网的发展现状出发，探讨IPV的成本、技术和未来趋势。我们认为钙钛矿光伏更适合室内应用，并回顾了一些制造高性能钙钛矿室内光伏器件（IPV）的策略。最后，我们还对钙钛矿IPV的长期发展提出了展望。
